The answer
At today's deposit of $605,084 this fund covers every draw on the horizon. Nothing more is required.
One recurrence, applied 10 times: balance = balance × (1 + 0.0%) + deposit − draws. Deposits are today’s figure, held flat. No solver and no goal-seek — the answers below are closed-form, so the same inputs always give the same figures.

A fund can look over-funded inside a six-year window and be correctly funded once the assets landing beyond it are on screen. The recommended contribution is computed on the full horizon, which is why this panel exists.
